COASTAL EROSION RISK ANALYSIS WITH EMPHASIS ON DAMAGE TO INSTALLED INFRASTRUCTURE IN THE COASTAL ZONE OF THE MUNICIPALITIES OF TIBAU AND GROSSOS/RN
Shoreline; Coastal Erosion; Risk; Geotechnologies
Coastal erosion and the associated risks have been the subject of study in various parts of the world. A large portion of the coastal strip in different countries is undergoing urbanization, which serves to highlight erosive processes, whether natural or induced by human activity in these spaces. The municipalities of Grossos and Tibau, located on the Northern coast, show signs of erosive processes impacting installed infrastructure, whether public or private. Additionally, the coastline has been undergoing intense anthropogenic occupation in recent years, mainly due to real estate projects such as multifamily condominiums.
The methodology used in the research was based on identifying the variation of the coastline over the last four decades using the Cassie Engine platform to identify areas with coastal erosion, conducting field data collection using geodetic GPS and drones, as well as using geotechnologies to process primary and secondary data, calculate risk areas, and generate thematic maps. Preliminary results indicate the occurrence of four zones with erosive potential during the study period (1985 to 2022), with some directly impacting the installed infrastructure along the coastal strip of the municipalities. This thesis aims to identify the risks of coastal erosion based on the variation of the coastline and the damage caused to infrastructure along the coast of the municipalities of Tibau and Grossos in the state of Rio Grande do Norte.
